Abstract
Recent results obtained by Keel et al. (1997) have provided a complete characterization of all stabilizing PID controllers for a given plant. This characterization has an elegant property: for a given fixed proportional gain, the set of all stabilizing integral and derivative gain values is the intersection of the admissible solutions of sets of linear inequalities. Based on this characterization, the design of non-fragile PID settings for enhancing the robustness of the closed-loop systems to perturbations in the controller coefficients is addressed
